Input position setting method, input position setting device, input position setting program, and information input system

An input position setting device for setting an input position for an instruction position by an instruction section on the basis of a pickup image data obtained by picking up an image of a display area when an operator instructs a predetermined position of the display area to be displayed by an image display device with the use of the instruction section, the device comprising:

• an instruction image area acquiring unit for acquiring the image area corresponding to the instruction section as an instruction image area from the pickup image data;
• an input position setting unit for detecting a position existing on a contour of the instruction image area, which is remotest from a reference position set in the instruction image area, as a remotest point and setting the input position on the basis of the remotest point;
• and
• an information display control unit for input position setting progress for generating input position setting progress information to show the operator the progress of setting the input position and superimposing the input position setting progress information on the image data to be displayed by the image display device.
